Biography:
I am a staff scientist at Lawrence Livermore National Laboratory, who leads a multidisciplinary team to study interfacial phenomena, including ion transport, degradation and mechanics, in a wide variety of electrochemical systems. A key emphasize of our research is to develop multiscale modeling framework to address how atomistic level of details, such as arrangement of atoms and local chemistry magnify at the microstructure level, and how microstructure features controlled by various processing methods influence the performance and structural integrity of the electrochemical cell at the device level. In addition, we have been actively developing methods to allow close-loop understanding and design of electrochemical interfaces through tightly coupled experiment-theory approach.

Brief Abstract:
This project aims to understand degradation at the electrolyte-electrode interfaces during cell preparation and electrochemical cycling. We will leverage various computational methods developed at LLNL to address how degradation precursors are formed during initial chemical or electrochemical reactions and how these precursors dynamically evolve to form an inhomogeneous solid electrolyte interphase (SEI). In addition to the understanding of SEI formation, we will elucidate the implication of SEI formation to ion transport kinetics and address the impact of microstructural features of the SEI.
